The first three items — formation of organic compounds, formation of DNA (or RNA) building blocks, and formation of cell membranes — allowed cells to form.
- Organic compounds provided the raw chemical building blocks.
- Formation of nucleic‑acid building blocks (initially RNA building blocks in most origin models, later DNA) enabled hereditary information and replication.
- Membranes (lipid vesicles/protocells) provided compartmentalization and a controlled internal environment.
The "last universal common ancestor" (LUCA) is not a cause but rather the earliest known descendant of those processes — the result of cellular emergence, not the factor that allowed cells to form.
